• 【Important】Alcohol concentration in your body will change over time. Don't be fooled by what describes on the internet and not just about calculating your weight, age and gender. If you test immediately after drinking, the results will fluctuate from high to low, and return to a stable level after about 15 minutes. If you drink a lot, it will take a long time to drop to zero. This is why you need to use a tester instead of estimating or passing your imagination.

Please wait 15 min. before checking, otherwise the reading will fluctuate from very high to low (then gradually decrease). This is due to the residual alcohol inside the mouth which enhance the result
